Genes affected

ENSG00000296036 (HGNC:):

MGMT (HGNC:7059): (O-6-methylguanine-DNA methyltransferase) Alkylating agents are potent carcinogens that can result in cell death, mutation and cancer. The protein encoded by this gene is a DNA repair protein that is involved in cellular defense against mutagenesis and toxicity from alkylating agents. The protein catalyzes transfer of methyl groups from O(6)-alkylguanine and other methylated moieties of the DNA to its own molecule, which repairs the toxic lesions. Methylation of the genes promoter has been associated with several cancer types, including colorectal cancer, lung cancer, lymphoma and glioblastoma. [provided by RefSeq, Sep 2015]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BS1: Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.0395 (6002/152100) while in subpopulation AMR AF = 0.0515 (787/15296). AF 95% confidence interval is 0.0485. There are 195 homozygotes in GnomAd4. There are 3176 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 195 gene
